Hi all. We have 7 bantam hens and no roos. We started with 2 and added 5 more 2 years later. Our oldest sebright, who is 4, has gone nuts. She is prancing around with her tail fluffed in a fan and aggressively attacking our buff brahma. We have removed Killer (our Brahma) from the coop as her head was bleeding pretty bad this morning. We are keeping her wound clean and keeping her away from the sebright. In the meantime, what can I do about my rooster-hen? She is a terrorist to our other hens, especially the more friendly birds.
